3M Corporation claims the bragging rights to the development of the Fresnel Lens
early in the 1960s. This lens is a key component in the overhead projector as we know
it today and helped launch an entire line of products. Since the 1960s, trainers and edu-
cators have found dozens of ways to incorporate the overhead projector into program
delivery.

Overhead Projector Usage Tips
The overhead projector is a very user friendly and effective training aid when incor-
porated correctly into your sessions. Just like any piece of equipment, however, you
should familiarize yourself with the actual projector you’ll be using because different
models vary slightly in design and operation. You should also rehearse using actual
transparencies that you’ll be using in the workshop. Some basics of usage include:

Select the appropriate type of projector. I find that models that project the light from
underneath the transparency work best. The alternative is a unit that bounces light
onto the transparency, then back up to a mirror (portable types). The latter can
create light glare in your eyes and prevents viewing of uncovered lines of text when
using the revelation technique. The portable type projector also prohibits the use of
the older LCD projection panels (no longer manufactured) if you plan to show a
computer-generated slideshow.
ALWAYS ensure that you have a spare bulb or backup projector before starting your
session.
Have at least a 25-foot extension cord with multiple outlets handy in case there is no
electrical outlet near the projector setup area.
Before participants arrive, check the focus of the projector by projecting a transparency
image and viewing it from different locations in the room.

Position the projector to allow a clear line of vision to the screen by participants.
Ensure that the screen is set up at a 90-degree angle to avoid the keystone effect.
Dim lights nearest the screen to ensure a sharper image and reduce glare on the pro-
jected image.
Do not stand between participants and the projection screen, or between the projector
and the screen.
When using a transparency, paraphrase the information by reading from the trans-
parency, not the screen. This keeps you facing your audience.

If you want to emphasize a key item, point to the transparency with a pen, pointer, or
other similar item rather than trying to stretch to reach it on the screen. Once you’ve
finished with the pointer, PUT IT DOWN! If you are nervous, I suggest you not use
a laser pointer because the dancing red dot on the screen will certainly let the audi-
ence know of your anxiety while distracting participants.
